  • MacBook Pro (13-inch, Late 2011), OS X Yosemite (10.10.5). I want to know if i can use DDR3 1600Mhz as the Mac Stated 'Your Mac contains 2 memory slots, each of which accepts a 1333 MHz DDR3 memory module. ' . Thanks – Chan CL Aug 25 '15 at 2:46

Generally you can use higher speed rated RAM above the rating specified by the manufacturer. So long as the type is the same and the only difference is the maximum frequency supported by the RAM stick then it should work fine with the CPU.
